Whether it's a key duplication or complete replacement, we come to you equipped to handle your Cadillac model efficiently and professionally.

Cadillac Key Replacement Guide

Misplacing or losing your Cadillac keys can be stressful, especially when you're stranded without a spare. This guide covers everything you need to know about lost Cadillac key replacement — from identifying your key type to choosing between a dealership or a locksmith. Learn how to use your VIN, what to expect in terms of cost, and how mobile locksmiths can help you get back on the road quickly and efficiently.

Traditional Cadillac Keys

Before the adoption of transponder technology, Cadillac vehicles relied on traditional mechanical metal keys without embedded chips. These standard keys operated door and ignition locks solely through physical bitting patterns and were easy to duplicate. Many Cadillac models from the late 1980s through the mid-1990s used this system before chip keys became the standard.

Some of the mechanical keyways used in older Cadillac models include:

• B44 – Found in vehicles like the 1989 Cadillac Brougham and Fleetwood
• B62 – Used on early 1990s Seville and DeVille models
• B51 – Common for door and trunk applications

Since these keys contain no transponder, duplication is simple and inexpensive. You can order pre-cut keys online using your key code or VIN. These keys typically cost between $9 and $25, depending on material and finish. You can also find programming tips for older Cadillac remotes and lock systems at Program Your Remote, which is helpful if you're dealing with remote fobs alongside mechanical keys.

If you'd rather go through a Cadillac dealership, they can cut a new mechanical key using archived key codes, provided you show proof of ownership. Most dealerships charge around $30 to $60 for mechanical key duplication depending on the model year and parts availability.

Locksmiths offer the fastest and most flexible option for cutting non-transponder Cadillac keys. They can cut a duplicate on-site or at their shop using your existing key or lock code. The average cost ranges from $20 to $45, and some locksmiths can even decode the lock if no key is present.

If you’ve lost all your keys, a new mechanical key can be created using the VIN. Both dealerships and locksmiths can look up the correct bitting pattern from the manufacturer’s database. This service typically costs $45 to $85, depending on how quickly the key code is retrieved and the type of blank required.

However, if the ignition has ever been replaced and is no longer matched to the original VIN, standard key code lookup won’t work. In these cases, the ignition may need to be replaced again to restore compatibility, with pricing from $180 to $300 depending on the vehicle model and labor rates.

Mechanical Cadillac keys offer a simple and affordable solution for classic vehicle owners. Whether you're restoring a vintage model or replacing a lost key, multiple duplication options are available to fit your budget and timeframe.

Cadillac Transponder Keys

Cadillac began introducing transponder keys in the late 1990s as part of General Motors' broader move to improve vehicle anti-theft systems. These early transponder keys—often referred to as "chip keys"—contain a tiny RFID chip in the plastic head of the key. When inserted into the ignition, the chip communicates with the vehicle's immobilizer system. If the signal isn’t recognized, the engine remains disabled. These systems were first seen on Cadillac models like the DeVille and Seville and eventually became standard across most of the lineup.

From the key blank reference guide, here are some verified non-laser cut transponder keyways and their associated FCC IDs used in Cadillac vehicles:

• B106-PT / FCC ID: KOBLEAR1XT – Used in 2003–2006 CTS and SRX models
• B99-PT / FCC ID: KOBLEAR1XT – Common on early 2000s Escalade, DeVille, and Seville
• B110-PT / FCC ID: KOBLEAR1XT – Compatible with late-1990s Catera and DeVille models

For Cadillac owners with at least one working key, ordering pre-cut keys online is a fast and economical way to get a duplicate. These keys can be made using the vehicle's key code or VIN. Pricing for pre-cut keys typically ranges from $30 to $60. In many older Cadillac models, if you have one working transponder key, you may be able to program an additional one using onboard procedures without visiting a dealership or locksmith.

If you'd prefer professional assistance, visiting a Cadillac dealership remains a reliable option. Most dealership parts departments can cut and program a new transponder key on-site. Pricing generally runs between $90 and $160, depending on the model and availability of OEM key blanks. If you're in Texas or any other major market, you can locate a nearby dealership for assistance.

Local locksmiths also offer competitive and convenient duplication services. Many mobile automotive locksmiths are equipped to cut and program Cadillac transponder keys right at your location. This route is typically less expensive than the dealership, with prices ranging from $70 to $130. Plus, you won’t need to tow your car or schedule a service appointment.

If you’ve lost all your keys, a full key replacement is still possible. A locksmith or dealership can use your VIN to cut and program a new transponder key. However, in these cases, the vehicle’s computer system must also be reprogrammed to accept the new key and reject the old one, ensuring the lost key no longer works. This service generally costs between $120 and $220.

One complication arises if the ignition was replaced previously. If the VIN and ignition are no longer synced, standard programming methods may fail. In such cases, ignition replacement may be necessary to restore compatibility. This could add $180 to $350 depending on the model and labor costs.

Understanding how Cadillac's original transponder systems work helps owners make smart decisions about duplication, loss recovery, and ignition servicing. Whether online, at a dealership, or through a mobile locksmith, affordable solutions are widely available.

Cadillac Laser Cut Keys

Cadillac introduced laser-cut, also known as sidewinder, keys in the mid-to-late 2000s as a security upgrade from traditional edge-cut transponder keys. These keys feature a distinctive internal groove and thicker body that makes them harder to duplicate and more secure against lock picking. Laser keys are typically paired with high-security immobilizer systems and often include built-in remotes or smart key functionality, depending on the model year.

According to key blank reference data, Cadillac uses several sidewinder key types and FCC IDs, including:

• HU100-PT – A common high-security blade used on models like the CTS, SRX, Escalade, and XTS from 2008 onward
• FCC ID: OUC6000066 – Found in flip-style remote laser keys for 2008–2013 Cadillac CTS and SRX
• FCC ID: OUC60270 – Used in some 2010–2014 DTS and Escalade models with sidewinder technology

For Cadillac owners who already have one working key, ordering pre-cut keys online can be a time-saving and cost-effective solution. These keys are precision-milled to your VIN or key code and shipped ready for programming. Prices for laser pre-cut keys typically range from $50 to $90. Unlike older models, most Cadillac vehicles with laser keys do not support onboard programming, so additional programming by a technician is necessary.

If you prefer working with a dealership, Cadillac dealerships offer key duplication and programming services using OEM parts. This option guarantees compatibility and includes full reprogramming of the transponder and remote features. The cost for key cutting and programming at a dealership typically runs between $150 and $280, depending on the model and key type.

Mobile automotive locksmiths are a practical alternative for Cadillac key duplication. Most modern locksmiths carry laser key cutting equipment and the diagnostic tools needed to program Cadillac transponder systems. Locksmiths often offer faster service at a lower cost, with full duplication and programming typically costing $120 to $200.

If you’ve lost all keys, a locksmith or dealership can generate a new key using your VIN. The new laser key must be cut precisely and then programmed to the vehicle’s onboard system. This service also deactivates any lost or stolen keys, ensuring they can no longer be used. Expect the total cost for this full replacement process to range from $180 to $300.

In situations where the ignition has been replaced in the past and no longer matches the original VIN, programming a new key may fail. When this happens, ignition replacement may be required to restore compatibility. The cost for this repair can add an additional $200 to $400 depending on labor and vehicle type.

Whether you're duplicating an existing key or replacing a lost one, understanding how Cadillac laser-cut key systems work helps ensure you choose the right service—dealer, locksmith, or online—to get back on the road securely.

Cadillac Smart Keys

Cadillac began incorporating proximity keys into its vehicles around the mid-2000s, with models like the CTS and STS leading the transition to keyless ignition systems. These smart keys enable push-to-start functionality and keyless entry, significantly enhancing both convenience and security. Verified FCC IDs for Cadillac smart keys include M3N5WY8609, used in Escalade and CTS models, HYQ2AB for the SRX, and NBG009768T, which is found in newer Escalade Platinum trims. Each FCC ID corresponds to a different circuit, frequency, and compatibility requirement, making correct identification crucial.

Drivers looking to save money often choose to order pre-cut keys online. These keys are precision-cut using the vehicle's VIN and shipped directly to the customer, typically costing between $85 and $130. Programming must still be done locally, but this option avoids dealer cutting fees.

If you prefer to go through a Cadillac dealership for a duplicate key, be prepared to pay for both the fob and service. Most dealerships charge between $180 and $350, depending on the model and fob type. In Austin, reputable options include:

• Covert Cadillac – 11750 Research Blvd
• Classic Cadillac – 6501 S IH-35 Frontage Rd
• Henna Auto Group – 8805 N Interstate 35

Austin also has numerous locksmiths equipped to duplicate Cadillac smart keys. Mobile locksmith services typically charge $120 to $180, which includes programming on-site. This can be a faster and more affordable solution, especially for older models without encrypted modules.

When all keys are lost, you’ll need to replace the key using the vehicle’s VIN. In such cases, the vehicle’s security module must be reprogrammed to accept the new fob and reject any lost or stolen ones. Dealerships and high-end locksmiths can both perform this service, though the dealer cost often exceeds $300.

It’s important to note that push-to-start ignition switch failures or replacements are not typically performed by locksmiths. These electrical systems fall under the scope of an automotive electrician or certified dealership technician.

Step-by-Step Lost Key Made Process

Losing your Cadillac key can be stressful, but getting a replacement doesn’t have to be. Follow these steps to get a new key made quickly and correctly:

Confirm the Type of Key Lost: First, determine whether your Cadillac used a standard metal key, a transponder key, a laser-cut sidewinder key, or a proximity smart key. This will help you understand what tools and services are required to replace it.

Gather Required Information: You’ll need your vehicle’s year, make, model, and VIN. Proof of ownership, such as your driver’s license and registration, is also necessary. Learn more about the process on our lost keys page.

Call a Locksmith or the Dealer: You can contact a mobile automotive locksmith for faster service or call a Cadillac dealership. Locksmiths are often less expensive and more convenient. Explore options at Automotive Locksmith.

Test the Key: Once the new key is made and programmed, test it on-site to ensure it starts the engine and unlocks the doors. Make sure all features are working before the technician leaves.

Make a Spare Key: Always duplicate your key to avoid another lockout. You can do this through a locksmith or order online via Duplicate Car Keys services.

Cadillac Ignition Repair and Replacement

Ignition issues can stop your Cadillac from starting and often require professional intervention. Common problems include:

Broken Key in Ignition: If your key breaks inside the ignition cylinder, do not attempt to remove it yourself. A professional locksmith can extract it safely and assess the cylinder for damage.

Key Stuck in Ignition: Sometimes the key won’t come out or turn. This is often due to worn wafers, steering lock issues, or internal debris. A technician can remove the ignition and service the tumblers as needed.

Key Won’t Turn: If the key won’t rotate, it might be the key itself or the cylinder. In either case, a trained professional can diagnose whether the issue is with the key or the ignition unit.

Burglary Damage: After attempted theft or vandalism, your ignition may be compromised. In such cases, an ignition replacement is often the safest option to restore functionality and security.

Dealership vs. Locksmith

Choosing between a dealership and a locksmith for Cadillac key services depends on your priorities:

• Dealerships provide OEM keys and official documentation but often require towing.
• Locksmiths offer mobile service, faster response, and access to high-quality aftermarket keys.

To work with a Cadillac dealer, you can contact:

• Covert Cadillac – 11750 Research Blvd
• Henna Chevrolet – 8805 N Interstate Hwy 35
• Mac Haik – 12920 US-183 Hwy N

Frequently Asked Questions

1. What should I do if I’ve lost my only Cadillac key?
If you've lost your only key, contact a professional locksmith or dealership to verify ownership and begin the replacement process. A new key can be cut and programmed to your Cadillac using your VIN. The old key can be deactivated so no one else can use it.

2. Can roadside assistance help if I'm locked out of my Cadillac?
Yes, many roadside assistance programs can help you gain access to your vehicle in a lockout situation. However, they typically cannot create or program new keys. If you need a new key, you'll still need to contact a locksmith or dealership.

3. What is a transponder key, and does my Cadillac use one?
A transponder key contains a chip that communicates with the vehicle’s immobilizer system. Most Cadillacs manufactured from the late 1990s onward use transponder keys for added security. If your key has a plastic head and was made after 1998, it likely contains a transponder.

4. Can I get a duplicate key made without visiting a dealership?
Yes. Many licensed locksmiths offer mobile key duplication services that match dealership quality. They can cut and program new keys for Cadillacs with or without transponders, often right at your location.

5. Will my insurance policy cover Cadillac key replacement?
Some comprehensive insurance policies may cover key replacement under theft, loss, or vandalism claims. Review your policy or contact your insurance provider to confirm if this benefit is included.

6. Can I open my trunk if I’ve lost the key?
Yes, a locksmith can access the trunk even if the key is lost. In some cases, the trunk can be opened manually or via interior access. For newer models with remote trunk releases, reprogramming the key fob may also restore this function.

7. Is it possible to program a Cadillac key myself?
Some older Cadillac models allow onboard programming if you have one working key. However, most newer transponder and smart keys require specialized diagnostic equipment for programming. DIY options are limited for modern Cadillacs.

8. What should I do if my key works in the doors but not in the ignition?
This could indicate a worn or faulty ignition cylinder. In such cases, a locksmith can inspect and either repair or replace the ignition system. You may also require reprogramming if your Cadillac uses a transponder system.

9. Do I need to tow my vehicle if I’ve lost all keys?
Not necessarily. Many mobile locksmiths offer on-site service and can cut and program keys without towing. This convenience is especially helpful in roadside assistance scenarios where fast response is critical.

10. Can I use a used Cadillac key fob I bought online?
Used fobs may not always be reprogrammable, depending on your Cadillac model and the original pairing status. It's best to consult a locksmith or dealership to confirm compatibility before purchasing used key fobs.
